I feel like I studied the LSP lifetime maximum, but I can't recall how it directly relates to the requirements here. Could it be option A?

I'm not entirely sure, but I think the overload bit passive could help with the R5 router not peering with the external network. It sounds familiar from practice questions.

I remember something about the passive-interface command being useful for preventing unnecessary hello packets. Maybe option E is one of the answers?
